Species coexistence depends on the comprehensive effects of biological properties and habitat heterogeneity. Based on a large-scale field survey (21°-35° N), we compared the differences on morphological and stoichiometric characteristics between the invasive aquatic species and the native co-occurring species , and examined the effects of environmental factors on such differences. The results showed that the coverage and importance value (IV) of . were all significantly greater than . (34.3% and 104.0%, respectively), whereas the height of . was significantly greater than . (13.8%). Moreover, the total nitrogen concentration (TN) and N:P of . were significantly greater than those of . (55.1% and 55.8%, respectively), whereas the total carbon concentration (TC) and C:N of . were significantly greater than those of . (4.1% and 83.8%, respectively). . coverage increased with the increases of longitude, and its abundance increased with the increases of water nitrate concentration and longitude, while its IV increased with the increases of water ammonium concentration. However, the coverage, abundance, and IV of . decreased with the increases of ammonium concentration. C:N of . decreased with the increase of ammonium concentration. Increased mean annual temperature and mean annual precipitation increased C:N but decreased N:P of . The C:P of both species decreased with the increases of ammonium concentration and electrical conductivity. N:P of . was little affected by environment. These results indicated that . had greater coverage and N absorption capacity than . , and that enriched water nitrogen would aggravate the invasion of . Meanwhile, . improved its C-assimilate reserves and chose the growth competition strategy for resisting . invasion under the superior hydrothermal conditions. Different responses to environmental changes contributed to their coexistence in aquatic ecosystem.

Human serum albumin (HSA) is a key protein implicates in various physiological and pathological conditions such as renal injury, diabetes mellitus. Herein, we report an AIE-active fluorescent probe (DNI-4) for detection of HSA with a "turn on" response covering visible and near-infrared region (500 - 800 nm). Combining with a triphenylamine and two 1,8-naphthalimide moieties, the chromophore segment of DNI-4 forms a "A-D-A" type molecular architecture with the twisted intramolecular charge transfer property.

Lipid peroxidation is a major process that determines the quality of various oil samples during their use and storage, in which the primary products are hydroperoxides (HP'). HP' are very stable compounds at ambient conditions and are harmful to human health. Therefore, the evaluation of the degree of oil oxidation is an excellent tool for ensuring food safety.

Particulate matter (PM) is a major component of ambient air pollution. PM exposure is linked to numerous adverse health effects, including chronic lung diseases. Air quality guidelines designed to regulate levels of ambient PM are currently based on the mass concentration of different particle sizes, independent of their origin and chemical composition.
